Title:
  qemu 1.0.50-2012.03-0ubuntu2 makes ARMv6k kernels crash

Status in QEMU:
  Fix Released
Status in “qemu-linaro” package in Ubuntu:
  Fix Released

Bug description:
  The Linux ARM kernel commit that starts causing the issue is:
  18b9dc130c33de2d1fd46bd668e67d0e1a544b16: ARM: vfp: add VFPv4 capability 
detection and populate elf_hwcap

  And is fixed in qemu with:
  06ed5d66f77f2794344c7dfd3d21a07e97f0b8fa: ARM: Permit any ARMv6K CPU to read 
the MVFR0 and MVFR1 VFP registers.

  qemu should be updated to at least v1.1.0 as soon as possible because
  all ARM realview kernels > 3.0 with VFP enabled will suffer from this
  issue.

  Thanks!
